Support for non-standard pricing regions?

Here's a suggestion for the pricing info. Currently SteamDB only shows a set of pre-defined regions, but they don't always match up with reality.

Examples:

Mount and Blade costs €9.99 in Italy, but €4.99 in Poland. Both are EU2.

GTA V costs $59.99 in the US, but $39.99 in India and $29.99 in China. SteamDB groups them all together as USD.

Would it be possible to detect and list these special cases?

Also, while I'm at it, it might be a good idea to not use Germany for EU1 prices. I've noticed that anytime a game is unavailable in DE due to censorship (like Dead Island), SteamDB doesn't show the EU1 price, even though it's available elsewhere in EU1.
